Abstract (en)
[origin: US2004070765A1] A light L from a light source 3 is transmitted through a sample cell S and is made incident into a spectroscopic portion 13. The spectroscopic portion 13 comprises interference filters 31-39 which transmit light components different in wavelengths and photodiodes 41-49 corresponding to the respective interference filters. Dielectric films to compose an interference filter have relatively satisfactory features to reflect a light component of wavelengths other than a light component of a wavelength to be transmitted. At each interference filter, an incident light is split into a light component to be transmitted and a light component to be reflected. By making the reflected light component into an incident light into a following-order interference filter, light components of nine wavelength types are detected.
